NIGP 92587: Sewage Collection, Treatment, and Disposal/Engineering

NIGP 92587 Sewage Collection, Treatment, And Disposal/Engineering, Item code, encompasses biosolids management, wastewater facility operations and upgrades, sewer rehabilitation and repair, and supporting engineering services that state and local governments procure to treat and dispose of sewage sludge and operate treatment infrastructure. Recent solicitations show municipalities and regional authorities actively buying biosolids disposal and recycling, wastewater treatment plant operations and process improvements, sewer line rehabilitation and replacement, pump station upgrades, and professional engineering design and construction administration for treatment facilities and collection systems. The issuing bodies span city and county departments (Sanford Florida, Wayne County Michigan, City of Phoenix, City of Ozark Missouri), state environmental agencies and departments (Maryland Environmental Service, Minnesota DNR, Florida Department of Transportation, California Department of Parks and Recreation), regional water authorities (Kansas Turnpike Authority, Beaufort Jasper Water & Sewer Authority), and special districts (Hamilton County Ohio). Engineering firms and treatment operators are the primary vendor class, alongside equipment suppliers and hauling contractors.

Recent activity concentrates in Florida, Georgia, Michigan, Ohio, Minnesota, and California. Representative opportunities include the City of Sanford's RFP for biosolids disposal and recycling (extended deadline August 6, 2026 with mandatory pre-bid July 30), Maryland Environmental Service's sealed-bid procurement for liquid emulsion polymer for biosolids dewatering (November 16, 2026), the City of Phoenix's RFQ for lift station construction administration and inspection services for a $7.9 million force main project (October 30, 2026 deadline), Hamilton County Ohio's progressive design-build RFQ for a high-rate treatment facility at the Little Miami Wastewater Treatment Plant (October 27, 2026), and Fulton County Georgia's ITB for 24/7 emergency sewage cleanup services with MBE/FBE set-asides of 11.49% and 2.62% (October 13, 2026). The mix of RFPs, RFQs, IFBs, and ITBs reflects both design-phase and operational-phase demand, with qualifications-based selections common for engineering and design-build work and unit-price or fixed-fee bids typical for operations, hauling, and specialized services.
